The launch is a team effort between the 4th Space Launch Squadron and the United Launch Alliance.

"I'm incredibly proud of all the hard work of the men and women of the 4th Space Launch Squadron team in preparing for this Atlas V mission," said Lt. Col. Brady Hauboldt, 4th Space Launch Squadron commander. "We've worked side-by side with United Launch Alliance and the entire 30th Space Wing to pull this campaign together over the last few months and we are now 'GO' for launch. We're all excited to have the opportunity to launch our newest Atlas V and demonstrate Team Vandenberg's continued contributions to space power."

The rocket will carry a national security payload for the National Reconnaissance Office.
